I don't have a clue why, but just a short time ago, I was lying in my hot
bath contemplating time spent on drilling rigs. I've come to realize that
I've forgotten more than most young guys know. But I digress.

Question: Why is it that 5" drill pipe comes in random lengths. Every
crane operator had that denim covered tally book in their back pocket, and
losing it could bring on severe consequences.

Out of everything we used, jars, collars, stabilizers, saver subs, fishing
tools, ........... the thing there was the most of was drilling pipe, and
that would seem to be the easiest to fabricate in standard lengths. Same
with casing.

The Pipe was fabricated in standard lengths. Then it left the
factory. Since then, I suspect it got tweaked, fixed, customized, and
da kind, but never uniformly.

Can anyone tell me?

Steve
